Product Description:

The MDD025A-N-100-N2K-040MC1 is a compact synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It serves as a drive element in digitally controlled automation axes, converting electrical commands from a compatible controller into precise rotary motion for positioning and speed regulation in industrial machinery. Its compact format suits smaller servo axes where limited installation space still requires accurate motion response. The motor is intended to work as part of a closed-loop drive system rather than as a stand-alone motion device.

The mounting interface uses a centering diameter of 40 mm, which helps align the housing accurately on the machine flange. Power and feedback conductors exit on Side A, and the motor is supplied with a connecting cable with a coupling unit for direct connection to the matching drive system. At standstill, the motor can deliver a continuous torque of 0.33 Nm under natural convection through its standard housing. The motor uses frame size 025 with the A-length stator, keeping the package short for compact axis layouts. The output is a keyway shaft without a secondary shaft end, and the rotor uses a standard balancing grade suited to high-speed operation.

A built-in blocking brake provides 1.0 Nm of static holding torque, which helps hold vertical or oscillating loads when input power is removed. During operation, the rotor can reach a nominal speed of 10000 rpm, and the drive controller uses resolver feedback for closed-loop current and velocity control. The motor is supplied without a shaft seal, so it is better suited to dry and clean operating areas where contaminants are limited. This arrangement keeps the mechanical interface simple and supports use with digital drive controllers that manage commutation and motion control outside the motor housing.
